Latest Patents
One of his latest patents is titled "Receiving apparatus and method for providing input bits of fast fourier transformer according to modulation." This technology aims to improve the efficiency of an OFDM system by analyzing the Bit Error Rate (BER) in wireless communication. It determines the minimum FFT input bit that results in a Signal-to-Noise Ratio (SNR) difference of 0.1 dB or below, in relation to a theoretical BER graph at a desired performance level.
Another notable patent is the "Multi-carrier transmitting apparatus and method for multicast service." This invention provides an apparatus and method for transmitting multiple carriers to deliver high-quality services to multicast-based service subscriber terminals. The method involves mapping first data for the multicast service and second data to different antennas, converting these into Intermediate Frequency (IF) signals, and then into Radio Frequency (RF) signals for transmission.
